JoNEs, a citizen of the United States, andv resident of and whosepost-oflice address is VVynnewood, in the county of Montgomery and Stateof Pennsylvania, have'invented certain new and useful Improvements inMethods of Heating and Purifying Water,

of which the following is a specification.

My invention relates to improvements in the methods of heatin water, andimprovements in feed water heaters, purifiers and regulators, andespecially to those instances Where the water of condensation is takenfrom the condenser and used over again.

The objectsvof my invention are, first, to prov de economical,convenient and effective ways and means for reheating the condensedwater and such supplemental raw water as may be necessary to'make up theamount re uired.

attain these objects by the ways and means illustrated and described inthe following specification and drawings, in which like numerals ofreference refer to like parts throughout the respective views.

Figure 1 is a top lan view of a combined heater, purifier and filterembodying my inventlon. Fig. 2 is an elevation thereof, showing aportion of the casing broken away and the interior parts chiefly insection. Figs. 3 and 4 are detail views showin float controlled valvesin both raw water and condensed water supplies.

Since the general structure of feed water heaters, etc., is well knownin the art, I do not illustrate those features which are common in thisdevice and which do not form a particular part of my improvement andwhich have already been described in various patents heretofore issued.

Referrin in detail to Fi 1,1-is aheater 2afilter ed; 3an outlet passage;4sep arator; 5steam inlet; 6inlet for raw water; 7exhaust to theatmosphere; 8 inlet for water coming from condensers, or other source,of partially heated water; 9- by-pass; 10.di-viding partition; 11dome offloat chamber; 11'-vent pipe leading from float chamber to upper part ofheater; l2fioat and mechanism; 13water trays on raw water side; 14watertrays on condensed water side; '15stand pipe; 16-

passages for steam in and around plate 10; 17valve in sup ly pipe.

Heretofore in most ieating devices the exhaust steam from the motors orother source has been introduced into the heater in such way as to heatonly the raw water which generally is at a com )aratively lowtemperature andnnust be heated up to nearly the temperature of the steam--say, 210. Owing to the impurity of this raw water, it should befiltered, and preferably chem cally treated, for the purpose of pre ci)itating and removing those im )urities, all of which is old in the artand therefore will not be more at length explained.

My improvement while retaining all the advantages of this old systemperforms with it and combines with it in the same. structure, amethod ofand means for utilizing the excess or surplus heat of the exhaust steam,for the purpose of heating the water of condensation, which may be takenfrom the condensers or from any other source, and Which is substantiallychemically and mechanically pure, and which is already at a hightemperature and therefore re uires comparatively little additional heat.of course, an advantage to heat both those supplies and qualities ofwater at about the same time and by the same steam supply, and theoperation of the device and method by which I accomplish this end is asfollows: I construct the dividing partition 10 in a feed water heater insuch a way as to substantially divide the same into two parts. Althoughthis partition does not entirely cutoff one part from the other,

it is meant to separate the condensed water which enters at acomparatively high temperature at one side of the heater from the rawwater entering at a comparatively low temperature at the other sidewhile allowing the circulation of steam on each side. *TlllSparticularly'because, as hashcen said, the condensed water is alreadypure while the raw water has yet to be treated and urified. For thisreason the partition as spaces about it orapertures m it through whichthe exhaust steam coming through V I ass after having warmed the waterdripping from the raw water trays 13, and thereupon heats the waterdripping from the condensed t is,

water trays -14 on the other side of the partition. This dripping,disinte ating or spraying effects a more rapid. an effectual heating ofboth raw and condensed water supplies. I refer to introduce this steamin the-first p aceat that side of the heater to which the raw water isfirst introduced,

since it is desirable that the coldest water i should receive the firstheat of the incoming steam, since the pure water from the condensers isalready very hot and therefore requires a smaller increment of heat fromthe steam in the heater, which increment is sufliciently found in thesteam after it has heated the raw water.

Since the condensed water is already purilied it need not be filteredand may'pass directly 'to the outlet or pump supply :3.

-()n the other hand, the raw water, after is such that the condensedwater is heated in one compartment and the make-up water in another, butbefore reaching the ump supply line the two waters are merged: and aftermerging maintain the desired working water line within the floatchamber.

In some cases it may be found desirable to use two floats'onecontrolling a valve in raw water supply ipe and the other controlling avalve in t e condensed water supply pipe, or one float may control bothvalves and theseishould be controlled from the common water line levelafter. the two supplies are combined. As usuall 0 erated, and as I haveillustrated it, t e oat should control the operation of the valvesupplying the raw water to the system, because the water from thesurface condenser is in practically all cases insufficient for therequirements of the boiler feed, and consequently raw, make-up water hasto be added, and it is to measure out accurately this make-u orsupplementary supply that the float an valve are employed.

The water from the condenser discharge enters a stand pipe, thencethrough a Water seal connection to one division ofthe system, while themake-up water passes through another connection to the other divi ion.

In order toinsure that there shall be suflicient quantity forthe umpsupply at all times, irrespective of't e condition of the filter-bed,and in the case that the amount of pure wateroffcondensation is notsufiicient for the demand, 'I provide a by-pass -9 extending from theraw water side of the heater about the filter-bed and discharging.

Where I have used the word dripping I mean a dividing up,disintegrating, spraying or breaking up of the supplied water intoparticles or minute streams.

I have shown one of the simplest forms of -by-passes, since theparticular form is not claimed by me in this application.

It will be understood that in thus explicitly describing the apparatusby which my method may be carried out, I do so merely to show a tangiblemeans for carrying out this method-the method being my invention asembodied in this application, while the peculiar apparatus forperforming this method forms the subject matter of an application filedby me July 8, 1907, bearing Serial No. 382,611.

I do not limit myself to any particular form, proportion, arrangement,construction, material, design or size in my invention, but

What I do claim and desire to Letters Patent is 1. The method of heatingand sup lying feed water which consists in introducing steam to a supplyof raw water, thereafter bringing the steam in contact with finelydivided water of condensation, purifying the raw water and bringing thewater from both protect by sources into the same outlet and thereafteruniting the ,two supplies.

2. The method of heating feed water, which consists in introducing steamto a su ply of raw water, thereafter bringing t e steam in contact withfinely divided and disintegrated water of condensation.

3. The method of heating, purifying and supplying feed water whichconsistsin bringing steam into contact with finelydivided anddisintegrated cold raw and hot condensed water successively; purifyingthe raw water and mixing the water from both sources.

4. The method of heatin feed water which consists in successive ysubmitting separate supplies of raw and condensed water in broken anddivided particles to a current of steam. I

5. The method of heating feed water which consists in introducing acurrent of steam to a supply of sprayed cold raw water and aseparate'supply of sprayed warm condensed water. I

6. The method ,of heating and supplying feed water, which consists inpermeating a supply of s rayed raw water with live steam,.

ticles of raw water, then introducing said steam to and diffusing thesame through a supply of broken and divided particles of condensedwater, then mixing the water from both sourcesand feeding it through acommon outlet. v

8. The method of heating and supplying a quantity of feed water, whichconsists 1n supplying a uniform and controlled quantity of both raw andcondensed water and ro'gressively breaking it up in broken and dividedparticles, then introducing steam to and progressively diffusin the samethrough the raw and condense Water successively, then mixing the Waterfrom both sources and feeding it through a common outlet.
